I hate to throw cold water on this as I *do* believe in natural
remedies. BUT saying "it certainly won't hurt" may be incorrect and
potentially harmful. Please remember that just because it's natural
doesn't mean it's harmless. For instance, that gorgeous foxglove in
your garden could kill a person who eats that "natural" plant as it
forms the basis for digitalis, a potent heart medicine.

And most important, have you asked permission or told your vet that
you are using Timmy's Tonic?

For instance, licorice is a well-known remedy for coughs and chest
complaints, especially bronchitis. Does your ferret have bronchitis?
More important, is your ferret on any heart meds? Licorice is
counterindicated for anyone taking lasix and it could prove fatal.
Are you using Timmy's Tonic daily? The Echinacea is recommended for
use periodically for one or two weeks at a time, rather than
continuously.

Yes, the quantities of each item may be minute but then what good is
the element? Please, before adding *anything* to your ferret's diet,
be sure to ask your vet and do your research!
